Heater/AC Poping Noise

[Raminator157]

This is kinda strange. Whenever I turn off my Heat or AC I hear a pop noise and it turns off. The Heat and AC seem to work fine though. Any Thoughts? Oh yea, like always I did a search before I posted.

"pop" noise from where? Are we talking inside the cab...like from under the dash somewhere? Or...somewhere in the engine compartment?

I cant pinpoint it. But its coming from under the dash. Like down towards the floor.

Sounds maybe like your blend door is sticking, poping open and closed as you switch back and forth threw the controls.

don't worry , the popping will soon stop, then you will be like us and have either only heat or only cold.

I am still trying to fix the darn blend door thing
